BOISE — The former president of the Idaho State Board of Education has defeated the incumbent superintendent of public instruction in the GOP primary.

Debbie Critchfield defeated Sherri Ybarra as well as former state Sen. Branden Durst in a race called Wednesday following voting in Tuesday’s primary.

Critchfield had about 40 percent of the vote followed by Durst with about 34 percent and Ybarra with about 26 percent.

Ybarra has served two terms overseeing the state’s education for some 300,000 K-12 students.

Critchfield will face Democrat Terry Gilbert in the November general election.
